We propose the completely non-destructive test using impact elastic waves for estimating the material properties of large diameter wood. In this test, splits in the wood have little effect on the measurement. We confirm the relationship between the surface and the cross section distributions of the wave velocity measured with the proposed test. Furthermore, we discuss the method to estimate the material properties based on the wave velocity of the wood surface. There is a possibility that the Young’s modulus can be estimated approximately by measuring 4 points equally dividing the wood surface in the circumferential direction.
